Are at least most supplied (even on the companion CD) or known freeware
clients smart enough to handle style 1 or 2 as needed?  (I'm thinking ethereal
as a likely example, since for many purposes it's _much_ nicer than snoop;
but I haven't looked at the code of either.)

AFAIK, a client can issue a DL_INFO_REQ to find out, among
other things, whether the device it opened corresponds to a style 1 or style 2
provider; but it wouldn't surprise me if some programs simply take one or
the other for granted.

Since Sun's network drivers have historically been mostly style 2, I trust the
conversion to style 1 as drivers are nemo-ified will be well publicized,
so that application developers would be reminded to ensure that their
code checks for style 1 vs style 2 providers and either doesn't or does issue
an attach, respectively.

On systems with lots of interfaces, will there be any problem with increased
consumption of major (?) device numbers with a style 1 provider?
